I am running a heartbeat... Asterisk 11.15.0 - same behaviour is noticed on 1.4.43 also

I issue a call through the API that does the below. just UserEvent and Hangup


   -- Executing [s@heartbeat:1] UserEvent("Local/s@heartbeat-0000000f;2", "HeartBeat, Noop") in new stack
    -- Executing [s@heartbeat:2] Hangup("Local/s@heartbeat-0000000f;2", "") in new stack
  == Spawn extension (heartbeat, s, 2) exited non-zero on 'Local/s@heartbeat-0000000f;2'
[Dec 16 13:57:01] ERROR[1956]: utils.c:1440 ast_careful_fwrite: fwrite() returned error: Broken pipe





I get "many" broken pipes (last line above) in the /var/log/asterisk/messages file.
Is there a way to more correctly close and not get that message?


Action: Originate\r\n
Channel: Local/s@smvoice-heartbeat/n\r\n
Context: heartbeat\r\n
Exten: s\r\n
Priority: 1\r\n



Thanks,


jerry

Assuming you are talking about the Asterisk Management Interface (AMI). 
 
I have seen many broken pipe messages cause by the AMI client closing the connection before reading the response from the server.  Some of the Asterisk Munin-Node plugins suffered from this problem.



After you issue your command, you need to read the response.  You should get a line that says '--END COMMNAD--' or an error response. Since the dialplan is executing, I doubt you will get an error.


Your client should issue a Logoff action, then read all the responses until it gets the 'Thanks for all the fish.' response.  Then close the socket.

Hi Dale,

I am in fact doing all the items you suggest. here is a log.


For normal commands I am logging off just fine.
Its just the heartbeat command I am getting an error on when logging out.


Thoughts?


Jerry

Jerry,

asterisk_execute() event_list=0 ret=55 last_command='Action: Logoff' Response: Error[CR ][LF ]Message: Missing action in request[CR ][LF ][CR ][LF ]



Shows an error.  Perhaps the originate did not complete before the logoff was sent?  I have never used original in AMI so it is just a guess.
